About Releases

The term ‘SEC Release’, in the context of the Smart Energy Code (SEC), is used in reference to any modifications or suite of modifications that are made to the SEC on the same implementation date. A SEC Release can include modifications to the SEC that have no system impacts (documentation only changes) and modifications to the SEC that do have system impacts. System impacting modifications are those that affect DCC and/or User Systems and/or Devices. System impacting modifications to the SEC can come from two sources:

  • Modification Proposals; and
  • modifications made by the Secretary of State (SoS) using Section 88 powers.

Why are releases needed?

Releases provide a mechanism by which multiple approved modifications to the SEC are implemented at once in a coordinated manner.

SEC Release Management Policy

SEC Section D10.7 (Release Management) requires the SEC Panel to establish a SEC Release Management Policy. This policy informs how approved Modification Proposals or suites of Modification Proposals are implemented via SEC Releases.

At the September 2019 meeting, the Panel approved the current version of the SEC Release Management Policy:

SEC Release cycle

Typically, new SEC content will be released three times a year. The scheduled release cycle will be:

ReleaseTimingType
February ReleaseLast Thursday in FebruarySEC Documentation Release
June ReleaseLast Thursday in JuneSEC Systems Release
November ReleaseFirst Thursday in NovemberSEC Systems Release

If required, additional ad-hoc releases of new SEC content may also occur outside of the scheduled release cycle. Such changes may relate to Modification Proposals that can be implemented in short timescales or where it relates to a specific point in the year, such as the beginning of a new regulatory year.

Smart Landscape Releases Plan-On-A-Page

The Smart Landscape Releases plan-on-a-page presents an overview of future changes to the SEC. This includes the different versions of the technical documentation (SMETS, CHTS, GBCS, DUIS and MMC) and when each version will be implemented. The plan-on-a-page consolidates critical information on all changes to the SEC on one page, to allow Parties to see how multiple changes interact. This plan is designed to be a live document and will be updated on a regular basis when new information is provided.

We welcome any feedback you have on this, to ensure it provides the information you need. Please email us at sec.change@gemserv.com with any comments you may have.

Release 2.0 Testing Documentation status tracker

In order to successfully test the content of Release 2.0 to ensure the changes and new functionality operate as expected, while ensuring that existing functionality and devices continue to operate release testing is required. A number of Testing Approach Documents for Release 2.0 have/are being produced which will set out how this testing will be undertaken. A tracker spreadsheet is provided below, and gives an overview of the current status of each testing document.

The below Release 2.0 Testing Approach Documents have been approved by the Secretary of State.
